Hürrem rushing to move into Valide's room was so frustrating.
The show needed a reason for Hürrem and Süleyman to be apart so Firuze can get together with Süleyman. But the reason they came up with was so annoying.
Hürrem wasn't that stupid to rush into that room. It serves no purpose, she is already the strongest woman in the harem and there is no one that she needs to show off to by getting the biggest room. And Süleyman would eventually let her move into that room anyways if she only didn't rush in there. She knew Süleyman wanted that room empty, for now at least. It was so annoying to see Hürrem make such a stupid decision that was out of character IMO.
